 short, thitk ami ijuiutud, forming a dense rusLttc like 

 an Echeveria; in midsummer the Ivs. are large, thin, 

 obovate and lax. The plant blooms freely in both 

 stages, but produces the largest fls. later. In the fall 

 the foliage again becomes a bulb-like mass of fleshy 

 Ivs., and so rests all winter. Burbidge found that 

 the plants can be readily propagated by these fleshy 

 Ivs., each one producing a new plant, as in the case of 

 the bulb scales of certain common lilies. These leaf 

 cuttings were placed by Burbidge in the live sphagnum 

 of orchid baskets. Young plants were potted in 2H-in. 

 pots of live sphagnum, using small crocks only. These 

 small pots may then be plunged in small shallow 

 orchid pans to prevent extremes of moisture and hung 

 up in the cool end of a Cattleya house. Burbidge has 

 also grown P. hirti flora in pans of sphagnum standing 

 in a saucer of water and treated to the hottest sunshine. 

 The fls. are said to last 8 or 9 weeks. 



Pinguicula belongs to the same family with Utric- 

 ularia, a group composed largely of aquatic plants 

 which capture minute creatures in little bladders that 

 are developed on the thread-like Ivs. Pinguicula differs 

 in the more terrestrial habit, the 4-5-parted calyx, 

 spreading position of the posterior lip of the corolla 

 and also in the anthers. Pinguicula is one of the very 

 few dicotyledonous plants with only 1 seed-leaf. The 

 fls. of Pinguicula are often reversed before and during 

 anthesis.

 rarely purplish violet," according to DC, 10-15 lines 

 long, 9 lines broad (3 or 4 times longer than in P. vttl- 

 garis ) ; lobes undulate ; palate with 1 or 2 white spots ; 

 spur straight, a trifle shorter than the broadly funnel- 

 shaped tube. Western Eu. G.C. III. 10:373. -Accord- 

 ing to Bentham, this is a large-fld. var. of P. vulgaris, 

 with longer spur and broader lobes, which in the west- 

 ern part of Eu. passes into the common form. 



hirtifldra, Tenore. Scapes3-4in. high: fls. 8 lines 

 and broad, lilac or rose (blue according to Tenore, and 

 shown as purple in B.M.), with a white tube; spur 

 straight or curved, about as long as the rest of the 

 corolla. S. Eu. B.M. 6785. Gn. 25, p. 290.-Possibly 

 distinguished from P. grandiflora by the color of the 

 tube, which is white outside and yellow in the throat.

 P. hirtiflora in the bright blue color and the retuse 

 lobes of the corolla, as also in the less globose capsule: 

 scapes 1-5 in. high: fls. bluish purple ("blue," writes 

 Hooker), about 6 lines long; spur nearly straight, about 



2 lines long or as long as the rest of the corolla. Wet
